In this example we will show you how to get the size of a HashSet in Java.
Codes
package com.beginner.examples;
import java.util.HashSet;
public class GetSizeOfHashSet {
public static void main(String[] args) {
// Create a HashSet object
HashSet sets = new HashSet();
sets.add("a");
sets.add("b");
sets.add("c");
System.out.println(sets.size()); // //get the size of a HashSet
}
}
